Answer:
Closest standard deviation of W = 4.11
Step-by-step explanation:
Randomly selected workers = n =300
Probability of workers arriving between 6:45 to 7:00 A.M = p = 6% = 0.06
According to binomial distribution:
mean = μ = n.p
= 300(0.06) = 18
variance = σ² = n.p(1-p)
= (300)(0.06)(1-0.06)
= (18)(0.94)
= 16.92
standard deviation = σ = 4.11
2 3/10 = 2.3
To get this number as a percent, we need to multiply it by 100: 2.3 is a whole number, and can be represented by fraction 2.3/1
A percentage is represented by a fraction over 100. So to transform 2.3/1 to a percentage, just multiply both numerator and denominator by 100, and you'll get 230/100.
So 2 3/10 is 230% as a percent.
